The league informed Whitner on Thursday that the hit by Whitner that flattened Jackson in Monday night’s game doesn’t merit a fine.

“Great news! I didn’t get fined! Thank you @nfl!,” Whitner said via Twitter upon learning the news.

This marks the third time this season that Whitner avoided a fine from the league for hits he delivered that were deemed infractions by game officials. The first two times came as a result of helmet-to-helmet blows.

Whitner wasn’t fined on one of those occasions. He successfully appealed a $21,000 fine in the other instance.

On Monday night against the Falcons, Whitner timed a screen pass for Jackson, arrived just as the ball got to Jackson and knocked him off his feet with a shoulder-led blow to the upper torso on Jackson.

An official called Whitner for unnecessary roughness on a play that looked as if it could have been called either way.

Defensive coordinator Vic Fangio said it’s for others to pass judgment. However, when informed that Whitner wasn’t fined for his hit, Fangio said: “There’s your answer.”

Whitner said after the game that Jackson wasn’t defenseless and that he led with his shoulder and hit Jackson in the chest.

“I don’t know what else you want me to do,” Whitner said after the 49ers beat the Falcons 34-24.

It’s third-and-1 at the Chiefs 14-yard line and the Raiders running game was doing well. Instead, Raiders threw incomplete, were pushed back by a penalty and then threw incomplete again in 21-13 defeat.
